## About the Role

 * Hands-on experience building agentic capability such as MCP servers, tools, skills, or connectors for other systems and agents to consume.
 * Hands-on experience with a major cloud, ideally Azure, including containers or serverless compute, infrastructure as code, CI/CD, identity, RBAC, and secret management.
 * Experience owning services in production - monitoring, incident investigation, upgrades, lifecycle management - and establishing evaluation and observability for AI systems.
 * Good judgement in a regulated environment, translating security, privacy, risk, and audit requirements into working technical controls.
 * Experience mentoring engineers and leading technical work without relying on reporting authority, and clear communication with engineers, control functions, and business stakeholders.

 * Azure AI Foundry, Azure OpenAI, Anthropic Claude, model gateways, inference routing, or agent orchestration platforms.
 * Snowflake, Microsoft Fabric / OneLake, or comparable governed enterprise data platforms.
 * TypeScript or a second production language, and front-end experience for user-facing AI applications.
 * Experience building internal developer platforms or golden-path patterns used by other engineering teams, or taking partner-built software into internal ownership.
